[目的]了解四川省德阳市男男性行为人群(MSM)的艾滋病病毒(HIV/AIDS)、丙型肝炎病毒(HCV)和梅毒螺旋体(梅毒)感染状况及性行为特征。[方法]2010年4～8月,对德阳市251名MSM进行问卷调查及血液样品收集,分别用联免疫吸附试验、蛋白印迹实验、快速血浆反应素环状卡片试验检测HIV、HCV梅毒感染情况。[结果]被调查对象中,HIV,HCV和梅毒的阳性率分别为16.33%(41/251),0.8%(2/251),14.34%(36/251);HIV和梅毒均阳性人员占4.4%(11/251),占感染HIV人数的25%(11/41);HCV和梅毒均阳性的人员占0.4%(1/251);距调查结束前6个月,与男性、女性均发生过性行为的MSM较多,在与女性发生性行为时安全套使用率为76.08%(35/46),低于其同男性发生性行为时安全套使用率91.3%(42/46)(χ2=3.903,P﹤0.05)。[结论]该市MSM人群3种病原体感染不容忽视,其高危性行为普遍存在,需要进一步加强艾滋病/性病宣传教育,预防二代传染。

[Results] The positive rates of HIV, HCV and syphilis were 16.33% (41/251), 0.8% (2/251) and 14.34% (36/251), respectively. The positive rates of HIV and syphilis were 4.4% % (11/251), accounting for 25% (11/41) of those infected with HIV; 0.4% (1/251) were positive for both HCV and syphilis; with males and females 6 months prior to the end of the survey Sexual behavior had more MSMs, condom use rate was 76.08% (35/46) when having sexual intercourse with women, which was lower than 91.3% (42/46) (χ2 = 3.903 , P <0.05).
